Comments Abstract: "However, on a per cell basis, R. prowazekii had 5.6 fg of RNA and 1500 ribosomes per cell, which was only about 8% of the amount of both stable RNA (71.2 fg) and ribosomes (24,000) per cell as was found in E. coli." P.117 left column: "Accordingly, as shown in Table 2, R. prowazekii had 5.6 fg of stable RNA and 1500 ribosomes per cell, which is only about 8% of the amount of stable RNA and ribosomes found in E. coli (71.2fg and 24 000 per cell). However, the cell volume of the rickettsiae is only about 8% of that of E. coli (0.09µm^3 vs 1.1µm^3, (Austin and Winkler, 1988))."
